Best known in manufactured-concrete production for its Envirocure technology, CDS has unveiled the R-O2 Drying System, whose reduced oxygen, superheated steam atmosphere serves as an energy-wise medium for bringing sand, gravel and stone moisture levels to zero.

CDS plans to offer the R-O2 in 30-, 50- and 100-ton/hour models.

High thermal efficiency and rapid cycle times enable the R-O2 (short for reduced oxygen) to cut net energy consumption at least 25 percent compared to the fluid bed or rotary drum equipment commonly deployed to dry coarse and fine aggregates in packaged concrete production. The patented drying system is based on technology CDS has leveraged in other manufacturing processes for more than a decade. It debuted earlier this year at the National Concrete Masonry Association’s ICON Expo 2018 – Machinery & Equipment Show in Indianapolis. Fellow exhibitor Columbia Machine, which engineers and furnishes dry mix packaging lines in addition to block & paver equipment, will collaborate with CDS as the primary R-O2 sales and service agent. — CDS Inc., Boonton, N.J.; www.cds-concrete.com
